Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): Valves are present in the arteries.
Reason (R): Arteries carry oxygenated blood from heart to different body parts except pulmonary artery.
The correct answer is option D, Assertion (A) is false but reason (R) is true.
Explanation:
Valves in the Arteries:
Valves are not present in the arteries. Valves are structures that help in maintaining the one-way flow of blood. They are present in veins, not in arteries. The valves in veins prevent the backflow of blood and ensure that it flows towards the heart. Arteries, on the other hand, have thick elastic walls that help in carrying oxygenated blood away from the heart to different parts of the body.
Function of Arteries:
Arteries are blood vessels that carry oxygenated blood away from the heart to various parts of the body. They are responsible for supplying oxygen and nutrients to the tissues and organs. Oxygenated blood is pumped out of the heart through the largest artery called the aorta. From the aorta, the oxygenated blood is distributed to smaller arteries throughout the body.
Pulmonary Artery:
The pulmonary artery is the only exception among the arteries. It carries deoxygenated blood from the heart to the lungs for oxygenation. Unlike other arteries, the pulmonary artery carries blood low in oxygen and high in carbon dioxide.
Conclusion:
In conclusion, valves are not present in the arteries. The function of arteries is to carry oxygenated blood from the heart to different body parts, except for the pulmonary artery which carries deoxygenated blood to the lungs. Therefore, Assertion (A) is false as valves are not present in the arteries, while Reason (R) is true as arteries carry oxygenated blood from the heart to different body parts except the pulmonary artery.
Reason (R): Arteries carry oxygenated blood from heart to different body parts except pulmonary artery.
The correct answer is option D, Assertion (A) is false but reason (R) is true.
